METHOD OF DELIVERING ILLUSTRATED LECTURES 0R SONGS.

Application filed March 1, 1922. Serial No. 540,351.

T 0 all whom it may concern.

Be it known that I, ALEXANDER FERDINAND VICTOR, a subject of the King of Sweden (having declared his intentions of becoming 5 a citizen of the United States), residing at New York, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Methods of Delivering Illustrated Lectures or Songs, of which the following is a full, clear, and exact descri tion.

y invention relates to the method of delivering illustrated lectures or songs by means of wireless telephony.

radiogram' lectures or songs or anything else, to audiences or persons having wireless receiving stations, and to illustrate the same by pictures projected upon a screen at the place where the lecture is presented. This I accomplish by the means hereinafter fully described and as particularly pointed out in the claims.

The drawing illustrates a diagrammatical a5 layout of the invention.

In the drawings A represents a transmitting apparatus that has a receiving horn B, of the usual construction, that is attached thereto by wires C, C, and this transmitting apparatus A is connected by wires D to a wireless transmitting set of wires E.

At the receiving end of the invention, there is a receiving set of wires a, that is connected by a wire b to the receiving apparatus a, and this receiving apparatus, 0, is connected by wires (2 and d to the horn or amplifier e. w

At the receiving end of'the method, referably in the same room as the amplier e, there is a stereopticon screen F, upon which pictures are projected from a stereopticon G by the operator during the lecture, that is being delivered by a lecturer l, into horn B.

The lecturer, I, has a castanet J in his hand, and when he desires the pictures changed he simply claps the castanets' together, and thus signals the operator for a change. Of course the lecturer could snap his fingers, or could speak his desire for a change. Any means that made a sound that would conveya signal could be satisfactorily employed.

The object of my invention is to project The sound transmitted is preferably of a different timbre from vocal sounds so that the same will not be noticed bye he audience, or if heard, will'be taken to interference that is common particularly from signals in number of receiving stations at the same time, and, could be received by radio stations that were not supplied with the picture apparatus. Such lectures, however. would be enjoyed by audiences to a much less extent, than when illustrated by pictures.

It will be understood that where I refer to lectures I intend to include therein songs,

or anything else than can be used by my 1n' vention.

What I claim as new is:

1. The combination with a wireless sending station from which vocal sounds are transmitted,-a-receiving station for said vocal sounds, a manually operated picture projecting apparatus located adjacent to the sound reproducer of the receiving station, and a manually controlled signal having a different characteristic from vocal sounds transmitted by wireless to the vicinity of the manually operated picture apparatus for the purpose of signaling to synchronize manually the movement of the pictures to accord with the vocal sounds.

2. The'combination with a wireless sending station and a receiving station, of a manually operated picture displaying apparatus located adjacent to the receiving station, and means for manually producing at the sending station sounds which serve as signals between the sending and the receiving stations.

In witness whereof I have hereunto set my hand this 21st day of February, 1922.

ALEXANDER FERDINAND VICTOR.
